Written By Benjamin Summers

A RECEnt BBC Future article explores the growing global interest in sauna and cold plunge therapy, drawing on centuries-old Nordic practices and modern scientific research.

it examines how the combination of intense heat (sauna) with rapid cold exposure (ice bath) may enhance physical, cardiovascular and mental health.

The piece also covers potential risks, emphasizing the importance of moderation and medical guidance, especially for people with high blood pressure or cardiovascular issues.
